O2 - What is Dissolved Oxygen?

Dissolved Oxygen or DO is a measure of water quality and is affected by water pollution. DO is also an important process control parameter used in biological treatment of waste water. The dissolved oxygen can be controlled by on-line DO meter to maintain effective treatment whilst a field portable DO meter enable testing of water to identify water quality and to detect water pollution.
